BARBERS CHAIR.

SPECIFICATION forming part of Letters Patent No. 612,089, dated October1 1, 1898.

Application filed December 21, 1897. Serial N0.662,800- (No model.)

To all whom, it may concern.-

Be it known that-I, TIMOTHY J. COLLINS, of Toledo, county of Lucas, andState of Ohio, have invented certain new and useful Improvements inBarbers Chairs and I do hereby declare that the following is a full,clear, and exact description of the invention, which will enable othersskilled in the art to which it appertains to make and use the same,reference being had to the accompanying drawings, and to the numerals ofreference marked thereon, which form part of this specification.

My invention relates to a barbers chair, and has for its object toprovide simple and inexpensive means for tilting or setting the chair atvarious angles and locking the same in inclined positions.

A further object is to adapt the body of the chair to rotatehorizontally upon its base irrespective of the inclination and providemeans for locking the same in any desired position upon the base.

A further object is to adapt the locking mechanisms for tilting androtating to be operated upon severally by one lever without affectingthe other mechanism.

In the drawings, Figure 1 is a perspective view of the chair. Fig. 2 isa rear elevation of the tilting and locking mechanism, also of theoperating-lever. Fig. 3 is a vertical section on the line w as, Fig. 2.Fig. 4 is an enlarged detail of the locking mechanism. Fig. 5 is a likeview. Fig. 6 is a plan view of the bed-plate. Fig. 7 is an elevation ofthe bottom plate. Fig. 8 is a plan View of the holding-plate. Fig. 9 isan elevation of the droppin for the horizontal locking mechanism. Fig.10 is an enlarged detail of the duplex-camoperating and horizontallocking and tilting mechanism. Fig. 11 is an elevation of the arborcam-plate. Fig. 12 is a side elevation of the cam-plate secured to thearbor.

In carrying out my invention I secure to the base 1 a bed-plate 2,having a plurality of circumferentially-spaced holes 3. Integral withthe body of the bed-plate there is a projection 4: upon the face, havingan oblique inner surface coincident with the oblique portion 5 of theturn-table 6, secured to the arbor 7, which passes centrally through thebase 1, and is held in vertical alinement by a plate 8, secured to theunder side of the base 1.

9 designates the frame of the chair, having secured upon the inner sidesprojecting lugs 10 in coincident alinement, and journaled upon thereduced portion 11 of the lugs is a supporting-bracket 12, secured tothe turntable 6 by bolts 13. To the rearbar 14. of frame 9 there issecured a yoke 15, wherein is pivotally mounted a circular bar 16,having a plurality of serrations 17 upon the upper surface correspondingto the number of inclinations of thebody of the chair. The circular barpasses through a slot 19, centrally located in the arbor 7 above theturn-table. The circular bar is also slotted, as shown at 20, wherebythe tilting of the chair is limited by the pin 21, inserted in the slotand passing diametrically through the arbor 7. To the top portion of thearbor there is secured a bracketarm 22, having a pendent circularportion 23, wherein is secured a spring 24, pressing against acoincident circular surface 25, see cured t0 the frame 9. The object ofthe spring is to relieve the pressure of a person sitting in the chair,making it easier for tilting. Integral with the turn-table 6 is anannular boss 26. The aperture of the boss coincides with the holes 3 ofthe bed-plate 2, and located within the aperture is a pin 27, having aprojecting head 28. Secured to the ar1n29 of the bracket 12 is a metalportion 30, having projecting flanges 31 at right angles to the bodyportion and integral therewith, and j ournaled within these flanges isthe cam-arbor 32, having secured at its inner end, next to the arbor 7,a duplex cam 32. The larger portion 34 of the cam is adapted to lift ordisengage the circular drop-pawl 35, loosely mounted upon the arbor 7and engaging the coincident serrations 17 of the circular bar 16. Theshort cam 36 is adapted to engage the circular head 28 of the drop-pin27. Adjoining the journal 37 there is mounted upon the arbor a circularcollet 38, having a pin 39 in coincidence with a groove or camdepression 40, formed upon the opposite face of the journal 37, wherebyupon the rotation of the cam-arbor 32 by means of thehand-lever 41 theshort cam 36- is allowed to come in contact with the circular head 28 ofthe drop-pin 27.

In operation the normal position of the chair is as shown in Fig. 4. Thehand-lever 41 is in a vertical position. The horizontal locking-pin isshown engaging the aperture in the bed-plate 2, thereby preventingrotation of the chair. To disengage the pin, the handle is forced in thedirection indicated by the arrow 42, causing the arbor to rotate in thesame direction and the pin 39 to drop into the grooved slot, bringingthe cam portion 36 in vertical alinement with the projecting head 28,whereby further movement of the handle in the direction indicated by thearrow 42 will lift the pin from its locking position, allowinghorizontal rotation of the chair. The tilting mechanism is released byforcing the lever in an opposite direction, as indicated by the arrow43, whereby the short cam-lever is depressed and the larger portion 34is raised until it contacts with the drop-pawl 35, thereby disengagingthe same from the serrations of the circular bar 16 and allowing tiltingof the pivoted chair upon the bracket 12.

It will be seen that the cam-arbor is adapted to lateral movement and isnormally held to the journal 37 by a spring 44, encircling the arbor andinterposed between the journal 45 and the lever 41, thereby causing thepin 39 to normally press against the side of the journal 37, causing theengagement or disengagement of the short cam 36, adapted to engage thehead of the drop-pin 27. It will also be seen that by the reversemovement of the lever 41 the locking mechanism is operated uponseverally and independently. The chair may be tilted and locked in anydesired position and rotate freely upon the bed-plate and locked in anydesired position, or the bedplate may be locked and the chair tilted inany desired position. The interposition of the spring between thestationary horizontal bracket 22 and a coincident bracket or looksecured to the frame 9 of the chair at the front will cause an easymovement toward the inclination by the compression of the spring causedby the weight of the occupant of the chair. The cam operating thelocking device may also be made separate and secured to the arbor 32independently, the smaller cam 36 being preferably secured to theoutside of the annular boss 26.

46 designates a support for the foot-rest 47.

What I claim is 1. In a barbers chair, a base, a bed-plate secured tothe base, a rotary plate j ournaled in the bed-plate, an arbor securedto the retary plate and j ournaled in the base, a bracket secured to therotary plate and the chair-body, a yoke secured to the rear frame of thechairbody, a curved bar pivotally secured to the yoke, and passingthrough an aperture in the arbor, and having serrations upon its upperedge, a vertically-movable drop-pawl mounted upon the arbor, adapted toengage the serrations upon the curved bar, and means for raising thepawl, a horizontal slot in the curved bar, and a pin passingdiametrically through the arbor and the slot of the curved bar.

2. In a barbers chair, a base, a bed-plate havingcireumferentially-spaced holes, a rotatable plate journaled in thebed-plate, having an annular boss formed on its upper face in verticalalinement with the holes in the bed-plate, a pin inserted in the boss,and adapted to enter the holes in the bed-plate when brought intocoincidence, an arbor j ournaled in the base, avertically-movabledroppawl, a bracket secured to the rotatable plate, a plate secured uponthe bracket, an arbor journaled in the plate, having a lever upon oneend, and a duplex cam upon the opposite end, adapted to engage eitherthe drop-pawl or the projecting head of the pin according to thedirection of movement of the lever.

3. In a barbers chair, a base, a chair-body the lever, and encirclingthe arbor, where by rotating the arbor, the projection of the collet ismade to enter the coincident depression formed upon the face of thejournal and the arbor is moved outwardly, thereby alining the camsecured to the inner end of the arbor, with the projecting head of thepin, a projecting arm secured to the upper portion of the verticalarbor, adapted to support a spring at its outer end, and a lug portionsecured to the frame of the chair in abutment to the spring.

In testimony that I claim the foregoing as my own I hereby affix mysignature in presence of two witnesses.

TIMOTHY J. COLLINS.
